How to draw text on the Windows taskbar
Problem/Question/Abstract:
Does anyone know how to write a text on the main taskbar in Win95 using Delphi 3.0?
Answer:
This modified splash procedure that I use draws text directly on the Start button. Perhaps it helps. I normally use it to draw splash text directly on screen. To do that, use DC:= GetDC(0):
procedure TForm1.Button1Click(Sender: TObject);
var
DC: hDC;
Size: TSize;
Font: hFont;
const
DispText = 'Test';
begin
DC := GetDC(GetDlgItem(FindWindow(PChar('Shell_TrayWnd'), nil), $130));
ShowMessage(IntToStr(GetDlgItem(FindWindow(PChar('Shell_TrayWnd'), nil), $130)));
SetBkMode(DC, TRANSPARENT);
Font := CreateFont(12, 10, 0, 0, 1000, 0, 0, 0, ANSI_CHARSET, OUT_DEVICE_PRECIS,
CLIP_DEFAULT_PRECIS, PROOF_QUALITY, DEFAULT_PITCH, 'ARIAL');
SelectObject(DC, Font);
SetTextColor(DC, RGB(128, 128, 0));
GetTextExtentPoint(DC, PChar(DispText), Length(DispText), Size);
TextOut(DC, 0, 0, PChar(DispText), Length(DispText));
DeleteObject(Font);
ReleaseDC(GetDlgItem(FindWindow(PChar('Shell_TrayWnd'), nil), $130), DC);
end;
